Single Ended Hall Effect Sensor Input 1.
Overcurrent Detection and Thermal Protection pin. An
internal open drain transistor pulls to GND when an
overcurrent on one of the High Side MOSFETs is
detected or during Thermal Protection.
Half Bridge 1 and Half Bridge 2 Source Pin. This pin
must be connected together with pin SENSE
B
to
Power Ground through a sensing power resistor.
RC Network Pin. A parallel RC network connected
between this pin and ground sets the Current
Controller OFF-Time.

Ground terminals. On PowerDIP24 and SO24
packages, these pins are also used for heat
dissipation toward the PCB. On PowerSO36 package
the slug is connected on these pins.
Frequency-to-Voltage open drain output. Every pulse
from pin H
1
is shaped as a fixed and adjustable length
pulse.
RC Network Pin. A parallel RC network connected
between this pin and ground sets the duration of the
Monostable Pulse used for the Frequency-to-Voltage
converter.
